This is the best piece I’ve read about impeachment lately – read the whole thing.
For a long time, I was on the fence about impeachment. A couple of things that swayed me are mentioned in the article linked above. First, left to his own devices, Trump will drive the media narrative and suck up all of the media oxygen in the next 15 months. A set of impeachment hearings by one House committee meeting on a regular schedule with good counsel driving hard questions–not a bunch of different committees meeting on occasion with grandstanding preening questioners–will put Trump’s crimes on the front page of newspapers and lead the nightly news. Trump will have to respond, and he’ll look guilty and weak. Second, even when the Senate votes against conviction, vulnerable Senators like McSally, Collins and Gardner will have to take an actual vote. They would rather tsk-tsk about Trump and do nothing – a vote puts them in a tough position a few months before the election.
Third, it’s the right thing to do, and Congress needs to do its duty. Pelosi’s reticence is probably driven in part by pushback from members who would rather do nothing and hope that Trump just won’t be re-elected. That might happen, but a lot of Democrats went out of their way to vote for candidates who promised to do something about Trump, and Congress doing nothing is going to suppress Democratic turnout. There are also some “independent” low information voters who might learn something from the Mueller report being read into the record, one day at a time. (And, btw, fuck yes this committee must get Mueller to testify, if only to read his report into the record. Look at the effect of his press conference, which essentially just repeated some facts from his report, yet still enraged Trump and led the newscasts.)
Finally, the House also needs to pass all the legislation that Democrats promised, and Presidential candidates need to talk about how they would sign those bills if they were elected. Maybe Democrats’ policy messages will be drowned out by the impeachment hearings, but we already run the risk of Trump’s inane tweeting drowning them out.
